Frisbee fungus is a levitating, bioluminescent organism found in tropical jungles, fetid swamps, and mouldering ruins. It generally floats docilely above the landscape, drifting with the winds...but upon sensing prey, the creature rockets with frightening speed.

Frisbee fungi feed off psychic energies, and target those with 3+ Mental Mutations and/or WIL scores of 15+. They fixate on the head, lashing out with probing tentacles that invade any and all orifices to leech the brains within. Those struck by 3 or more frisbee fungus tentacles in any given combat round not only take the appropriate damage, but lose 1d4 WIL points upon a failed Saving Throw Vs. Stun. Anyone reduced to 0 WIL collapses in a drooling, brain-dead heap.
